Scat Pack Power Packages

We offer five different Scat Pack performance packages to meet a variety of needs. Here’s an overview to help you choose the right one for your build:

DT515 Package (Base Pump Gas Package)
The DT515 is our most affordable option you can run without upgrading injectors, which helps keep costs down. This package is simple to install, and many customers complete it themselves. Running on 91/93-octane fuel, it provides about 30 wheel horsepower over stock. If you’re starting on a budget, this is a great entry point for your build.

DT 525 Package (Performance Pump Gas Package)
The DT525 takes performance up a notch, adding 40 wheel horsepower over stock while still running on 91/93-octane fuel. This package includes longtube headers for better exhaust flow, a cold air intake, and custom engine and transmission tuning for sharper response. It’s the perfect next step for Scat Pack owners looking for more power and a deeper, more aggressive exhaust note. If you’re ready to push your build further, the DT525 delivers the performance gains you’re after.

DT605 Package (Advanced Power Package)
For those chasing serious horsepower, the DT605 delivers 80-90 WHP gains with a combination of bolt-ons and custom tuning. This package includes a Blueprint intake manifold, BBK throttle body, JLT cold air intake, and a custom grind cam kit, all working together for maximum airflow and power. With engine and transmission calibration, plus our RTD+ tuning and PCM unlock, your Scat Pack will pull harder and rev faster than ever. If you’re ready to take your build to the next level, the DT605 is the ultimate performance upgrade.

DT525E Package (E85 Flex Fuel Power Package)
Take your Scat Pack to the next level with E85 power! The DT525E is built for maximum performance on ethanol, delivering stronger pulls and sharper throttle response. With FIC 650cc injectors, a JLT cold air intake, and custom engine and transmission tuning, this package unlocks serious horsepower gains. Prefer pump gas? No problem—91/93 octane tunes are included too. Designed for easy installation and tested to perfection, the DT525E is the perfect upgrade for those ready to embrace flex-fuel power and performance.

DT535E Package (E85 Performance Package with Longtube Headers)
Take your Scat Pack to the next level with the DT535E, delivering 55+ wheel horsepower on E85. This package combines a JLT cold air intake, longtube headers, FIC 650cc injectors, and our custom engine tuning to extract every last ounce of performance. With our RTD tuning device and dedicated E85 tune file, you’ll get stronger acceleration, a deeper exhaust note, and razor-sharp throttle response. If you want maximized power and efficiency, the DT535E is the upgrade your HEMI needs!

Unlike our Flex-Fuel packages where you can a mix of pump gas and E85, the Scat Pack packages do not have this ability. You can use either pump gas (91 or 93) or E85, but not both at the same time. Both the DT525E and DT535E come with two tune files, one for E85 and one for pump gas. So you would just need to make sure the vehicle has the appropriate tune file in it depending on the fuel you are using. The files are incredibly quick and easy to swap out though, thanks to the RTD device that is included in every Dusterhoff Racing Power Package.

We would consider the installation to be an intermediate-level job. If you have some mechanical aptitude and experience, the installation should be manageable. The main hurdle will be the Camshaft installation and headers that are included in some of our packages.
Installing the injectors is relatively straightforward—it requires removing four bolts on each side of the engine to take off the fuel rails, then simply popping in the new injectors and bolting everything back together.

We’ll be releasing installation walkthrough videos in the coming weeks, so keep an eye out for those!

Every Dusterhoff Racing Power Package includes PCM unlocking through HPTuners. Once you receive your RTD (Remote Tuning Device), simply plug it into the OBD port to read your truck’s stock file. After that, you’ll need to remove the PCM and send it to HPTuners for unlocking. The entire process takes about a week, including shipping, so be sure to plan ahead.

We are yet to see any failures on a Scat Pack with just our package installed, outside of any manufacturer defects such as the lifters, a common issue in the 392 engine, which is why we recommend swapping to our OEM Hellcat Lifters. When adding new parts or modifying the vehicle any further make sure to reach out to see if you will need a tuning revision.

As far as drivability, around town the car will drive the exact same as stock. When you get into the gas, that’s when you will notice the massive differences in performance.

You don’t need anything else with the package, as it comes with everything you need. That said, there are a few other mods that will help increase performance and help the longevity of your motor.

For our more aggressive camshafts included in select Scat Pack Power Packages, we highly recommend upgrading to a 3600 Stall Speed Converter by Sipple Speed. This swap isn’t just about performance—it’s about improving drivability, making your build smoother and more responsive while cruising around town. A higher stall converter helps your HEMI get into its powerband faster, reducing low-RPM sluggishness and making stop-and-go driving much more enjoyable. If you want to get the most out of your setup without sacrificing everyday drivability, this upgrade is a game-changer! 🔥


If you’re looking for a quick and effective upgrade for your 392, the Brisk ER12S Silver Racing Spark Plugs are a solid choice. Designed for high-performance applications, these plugs deliver a stronger, more consistent spark, improving throttle response and high-RPM performance. The silver core electrode dissipates heat faster than standard materials, helping to lower overall spark plug temperature and reduce strain on your ignition system. Whether you’re running pump gas, E85, or race fuel, these plugs fire reliably—even in extreme conditions. A simple swap, but a noticeable difference in performance!

Upgrading to Hellcat Lifters in a 6.4L HEMI is a smart move for anyone looking to enhance durability and performance, especially in modified builds pushing more power. Designed to handle the increased stress and high-RPM demands of the Hellcat platform, these lifters offer better valvetrain stability, improved oiling, and increased durability compared to the factory 6.4 lifters. Their upgraded internals allow for smoother operation at higher engine speeds, reducing the risk of valve float and ensuring consistent performance under load. The enhanced oiling design also helps with lubrication and heat dissipation, minimizing friction and wear over time. Whether you’re adding a bigger cam, increasing RPM limits, or just looking for a more reliable, high-performance setup, Hellcat lifters provide the strength and efficiency needed to handle the extra stress. If you’re serious about making power and keeping your 6.4 running strong, this upgrade is a no-brainer.

Adding headers to your Scat Pack isn’t just an upgrade—it’s a game-changer. High-flow stainless steel headers help your 6.4L HEMI breathe better, unlocking more horsepower, torque, and throttle response while delivering that deep, aggressive exhaust note every Mopar enthusiast craves. By reducing exhaust restrictions, headers allow for a more efficient burn, improving overall engine performance and even helping with fuel efficiency under normal driving conditions. Plus, with high-quality construction built to handle the heat and stress of performance driving, this is an upgrade that doesn’t just sound good—it lasts. If you want to maximize power and give your Scat Pack the voice it deserves, headers are the way to go!
